14 Chapter 1 Product information ENWW Print-cartridge information

The print cartridge is designed to simplify replacement of the major consumable parts. The print cartridge contains the printing mechanism and a supply of toner. At 5 percent page coverage, a standard print cartridge will print approximately 2,500 pages. As page coverage increases, yield decreases. These estimates are only approximate; usage conditions and print patterns can cause results to vary.

Refilled print cartridges While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty period or while the product is under a maintenance contract, it is not recommended for the following reasons: ● Repairs resulting from the use of refilled cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. ● Hewlett-Packard has no controls or processes to ensure that a refilled cartridge functions at the high level of reliability of a new HP LaserJet print cartridge. Hewlett-Packard also cannot predict the long-term reliability effect on the product from using different toner formulations found in refilled cartridges. ● The print quality of HP LaserJet print cartridges influences the customer’s perception of the product. Hewlett-Packard has no control over the actual print quality of a refilled cartridge. ● Parts that are critical to print quality might not be replaced when the cartridge is refilled with toner.

HP LaserJet printing supplies In many countries/regions, this product's printing supplies (for example the print cartridge) can be returned to HP through the HP Printing Supplies Returns and Recycling Program. An easy-to-use and free take-back program is available in more than 30 countries/regions. Multilingual program information and instructions are included in every new HP LaserJet print cartridge and supplies package.

HP Printing Supplies Returns and Recycling Program information Since 1990, the HP Printing Supplies Returns and Recycling Program has collected millions of used LaserJet print cartridges that otherwise might have been discarded in the world's landfills. The HP LaserJet print cartridges and supplies are collected and bulk shipped to our resource and recovery partners, who disassemble the cartridges. Remaining materials are separated and converted into raw materials for use by other industries to make a variety of useful products. U.S. returns For a more environmentally responsible return of used cartridges and supplies, HP encourages the use of bulk returns. Simply bundle two or more cartridges together and use the single, pre-paid, pre-addressed UPS label that is supplied in the package that the new cartridge comes in.

Use the information in this section to choose the proper print media.

Paper and transparencies Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, holes, and curled or bent edges. Check the label on the paper package for details about the type of paper (such as bond or recycled). Some paper causes print-quality problems, jamming, or damage to the printer.

Note Do not use letterhead that is printed with low-temperature inks, such as those used in some types of thermography; raised letterhead; or colored paper or preprinted forms that use inks incompatible with the printer temperature (200° C, or 392° F, for 0.1 second).

Transparencies must be able to withstand 200° C (392° F), the printer's maximum temperature.

Labels

Note For best results, use only HP-brand labels. To order HP supplies, visit http://www.hp.com.

When selecting labels, consider the following factors: ● Adhesives: The adhesive material should be stable at 200° C (392° F), the product's maximum temperature. ● Arrangement: Use only labels that have no exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams. ● Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction. ● Condition: Do not use labels that contain wrinkles, bubbles, or other indications of separation. Never use a sheet of labels that has already been run through the printer.

Envelopes Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends on the quality of the envelopes. When selecting envelopes, consider the following factors: ● Weight: The weight of the envelope paper should not exceed 105 g/m2 (28 lb), or jamming might result. ● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl and should not contain air. Envelopes that trap air can cause problems. ● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise damaged. ● Sizes: Supported envelope sizes range from 90 by 160 mm (3.5 by 6.3 inches) to 178 by 254 mm (7 by 10 inches). Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle during printing.

ENWW Guidelines for using media 37 Envelopes with double-side seams An envelope with double-side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style is more likely to wrinkle during printing. Make sure that the seam extends all the way to the corner of the envelope as shown in the following illustration:

Envelopes with adhesive strips or flaps Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives that are compatible with the heat (200° C, or 392° F) and pressure in the printer. The extra flaps and strips might cause wrinkling, creasing, or jams.

Envelope storage Store envelopes flat to ensure good print quality. If air is trapped in and envelope, creating an air bubble, the envelope might wrinkle during printing.

Card stock and heavy media Some card stock performs better than others because the construction is better suited for feeding through a laser device. For optimum performance, do not use media that is heavier than 163 g/m 2 (43 lb). Media that is too heavy might cause misfeeds, stacking problems, jams, poor toner fusing, poor print quality, or excessive mechanical wear.

Note You might be able to print on heavier media if you do not fill the input tray to capacity and if you use media that has a smoothness rating of 100 to 180 Sheffield. Use the straight-through paper path for heavier media.

Card stock construction ● Smoothness: 135 to163 g/m 2 (36 to 43 lb) card stock should have a smoothness rating of 100 to 180 Sheffield. 60 to 135 g/m 2 (16 to 36 lb) card stock should have a smoothness rating of 100 to 250 Sheffield. ● Construction: Card stock should lie flat with less than 5 mm (0.2 inch) of curl.

38 Chapter 2 Operation ENWW ● Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged. ● Sizes: Use only card stock within the following size range: – Minimum: 76 by 127 mm (3 by 5 inches) – Maximum: 216 by 356 mm (8.5 by 14 inches)

Card stock guidelines ● If the card stock curls or jams, use the straight-through output path. ● Set margins at least 2 mm (0.08 inch) away from the edges.

ENWW Guidelines for using media 39 Loading media

This section provides information about loading media in the input trays.

Media input tray The media input tray holds up to 250 sheets of 75-g/m2 (20-lb) paper or a 25-mm (0.98-inch) stack of heavier media. Load media with the top forward and the side to be printed on facing up. To prevent jams and skew, always adjust the side media guides.

Priority input tray The priority input tray holds up to ten pages of 75-g/m2 (20-lb) paper or one envelope, transparency, or card. Load media with the top forward and the side to be printed on facing up. To prevent jams and skew, always adjust the side media guides. If you try to print on media that is wrinkled, folded, or damaged in any way, a jam might occur. See the user guide on the product CD for more information.

Note When you add new media, make sure that you remove all of the media from the input tray and straighten the stack of new media. This helps prevent multiple sheets of media from feeding through the printer at one time, reducing jams.

Specific types of media ● Transparencies and labels: Load transparencies and labels with the top forward and the side to be printed on facing up. See the user guide on the product CD for more information. ● Envelopes: Load envelopes with the narrow, stamp side forward and the side to be printed on facing up. See the user guide on the product CD for more information. ● Letterhead and preprinted forms: Load with the top forward and the side to be printed on facing up. See the user guide for more information. ● Cards and custom-sized media: Load with the narrow side forward and the side to be printed on facing up. See the user guide on the product CD for more information.

40 Chapter 2 Operation ENWW Selecting originals for the automatic document feeder (ADF)

Use either the ADF or the flatbed scanner for most copying, scanning, and faxing needs.

Specifications for ADF originals ● Input capacity: The ADF holds up to 50 sheets of flat, 60- to 90- g/m2 (16- to 24-pound) plain paper. ● Media size: Use only plain paper that is within the following size range: – Minimum: 127 mm by 127 mm (5 by 5 inches) – Maximum: 215.9 mm by 381 mm (8.5 by 15 inches)

Note You must use the flatbed to scan or copy small or delicate originals (such as newsprint, business cards, and photos), or documents that have tears, perforations, or punch holes. If you want to fax such items, first make a copy on the flatbed and then fax the copy.

Perform the following actions to minimize the possibility of jams: ● Remove self-stick notes. ● Remove staples and paper clips. ● Straighten any curls, folds, or wrinkles in documents before putting them into the document feeder tray. ● Do not insert any document that contains glue, correction fluid, or wet ink. ● Do not insert gum-backed paper or labels. ● Avoid multiple-copy forms. ● Do not scan originals that are larger or smaller than supported size limitations. See the user guide on the product CD for more information.

Note To obtain good results, it is important to use the correct re-entry and color settings for the job. See the user guide on the product CD for more information.

ENWW Selecting originals for the automatic document feeder (ADF) 41 Media information for the flatbed

Use the flatbed scanner for copying, scanning, and faxing if the media is fragile, thin, thick, or damaged (folded, wrinkled), or to produce a high-quality copy or file. The flatbed scanner provides the best copy and scan quality. The flatbed has no minimum size specification, and accepts a maximum size of legal-size media (215.9 mm by 355.6 mm, or 8.5 inches by 14 inches). In order to make a copy of a legal-size document, the paper size must be changed by using the PAPER SIZE button. Otherwise, the copy will be cropped to the default paper size.

42 Chapter 2 Operation ENWW Loading originals to copy or scan

Use these instructions to load originals into the product for copying or scanning. For the best- quality scans and copies, use the flatbed scanner. See Selecting originals for the automatic document feeder (ADF) for guidelines to choose original documents for scanning and copying.

To load originals onto the flatbed scanner 1. Make sure that the ADF is clear and does not hold media. 2. Lift the flatbed scanner cover. 3. Place the original document face-down on the flatbed scanner, with the top, left corner of the document located in the lower-right corner of the glass. 4. Gently close the lid. 5. The document is ready to be copied or scanned.

CAUTION To prevent damage to the product, do not allow the scanner lid to fall onto the flatbed scanner surface. Always close the scanner lid when the product is not in use.

To load originals into the ADF input tray The ADF capacity is up to 50 sheets of 75-g/m2 (20-lb) media (depending on the thickness of the media), or until the ADF input tray is full. The minimum size for media in the ADF is 127 by 127 mm (5 by 5 inches). For smaller sizes, use the flatbed scanner. The maximum size for media in the ADF is 215.9 mm wide by 381 mm long (8.5 by 15 inches). 1. Make sure the flatbed scanner is clear and does not hold media. 2. Close the flatbed scanner cover and put the top end of the original media stack into the ADF input tray, with the media stack face-up and the first page to be scanned, copied, or faxed on top of the stack. 3. Slide the media stack into the ADF until the media does not move any farther.

ENWW Loading originals to copy or scan 43 4. Adjust the media guides until they are snug against the sides of the stack.

5. The document is now ready to be copied or scanned. 6. After scanning, the document is delivered to the output tray in the correct order.

44 Chapter 2 Operation ENWW Printer output paths

The HP LaserJet 3380 all-in-one has two output paths. Use the main output bin when printing normal and large, collated documents. Use the straight-through output path when printing envelopes, transparencies, heavy media, or any media that tends to curl when printed.

Output bin and straight-through output path The output bin is located between the scanner and the printer. Printed media is collected here in the correct sequence when the straight-through output door is closed. To use the straight-through output path, open the straight-through output door on the rear of the product. Multipage documents are delivered in reverse order when the straight-through output door is open.

Figure 2-6. Output bin

Figure 2-7. Straight-through output path

72 Chapter 4 Operational overview ENWW Formatter system

The formatter coordinates the major systems. It is responsible for the following tasks or actions: ● controlling the motor controller board ● formatting and controlling copies ● receiving and processing print data from the printer interface ● monitoring the control panel and relaying printer-status information ● developing and coordinating data placement and timing with the print engine ● communicating with the host computer through the bidirectional interface ● communicating fax data to and from the LIU The formatter receives print data from the bidirectional enhanced capabilities port (ECP) mode interface or universal serial bus (USB) interface and converts it into a dot image. The ECU synchronizes the image-formation system with the paper-feed system and signals the formatter to send the print-image data. The formatter sends the print-image data (dots) in the form of a video signal, and the printing process begins.

Central processing unit The formatter incorporates an embedded 32-bit Coldfire V4e processor operating at 90 MHz.

Line interface unit (LIU) The LIU provides the required safety isolation, signal coupling, and impedance matching between the telephone line and the modem chipset that is located on the formatter.

Motor controller PCA The motor controller PCA contains motor-driver circuitry for the ADF motor and the scan- module position motor. The motor controller PCA also provides electrical interface from the formatter to the control-panel PCA and to the speaker.

Flash memory The formatter system includes firmware code that controls the product. The code is stored in flash memory, which allows the firmware code to be recovered or updated. The firmware update and recovery process is described in Troubleshooting.

Standard boot process When the product is unplugged or the power is off, the firmware code is stored on the formatter in two blocks. The first block of code is an executable boot block (about 64 K of code). The second block of code is a compressed version of the product control code. When the product is turned on, the boot block decompresses the product control code and stores it in RAM. Then the product performs a full startup with the control code running from RAM.

ENWW Formatter system 73 Product startup messages The LED display contains different messages depending upon the progress of the boot process:

Hewlett-Packard The product is starting up. Wait for the Ready message. <<< (Moving-cursor HP display)

Ready...... Product startup is complete and Begin using the product. the product is ready for use.

RAM The product contains two types of random-access memory (RAM): ● One bank of nonvolatile RAM (NVRAM) stores parameters. ● Dynamic random access memory (DRAM) provides temporary storage of the product program code along with copy, scan, and print data.

Parallel interface or universal serial bus (USB) interface The formatter receives incoming data through its bidirectional ECP or USB interface. These interfaces provide high-speed, two-way communication between the product and the host, allowing you to change product settings and monitor product status from the host computer.

Control panel The control panel consists of the following features: ● six groups of buttons to control fax, copy, scan, and configuration functionality ● a 2-by-16 LCD display that shows status, menus, and messages

● two front-panel status lights (one next to the CANCEL button and one next to the FAX/SEND button)

EconoMode (Draft mode) When you select EconoMode in the printer driver, the product uses less toner, which extends the life of the print cartridge. Using EconoMode produces a lighter image because less toner is on the page.

74 Chapter 4 Operational overview ENWW MEt HP Memory Enhancement technology (MEt) effectively doubles the standard memory through a variety of font- and data-compression methods.

Enhanced I/O The enhanced I/O (EIO) feature allows product memory to be used for storing data received from the host computer. When EIO is enabled, you can send more data to the product in shorter amounts of time, so that you can return to the software program more quickly. The EIO feature has the following options: ● Auto —the product uses EIO memory allocation to increase the speed of data transfer from the host computer to the product, if necessary. The default setting is Auto. ● Off —the minimum amount of product memory is used to store data that is sent from the host computer. ● Page Protect—the formatter creates the entire page image in page-buffer memory before physically moving the media through the printer. This process ensures that the entire page will be printed. Page complexity (ruling lines, complex graphics, or dense text) can exceed the printer’s ability to create the page image fast enough to keep pace with the image-formation process. If Page Protect is disabled and a page is too complex, the page might print in sections (for example, the top half on one page and the bottom half on the next page). Some print-data loss is likely in these instances, and an error message will appear on the control-panel display.

PJL overview Printer job language (PJL) is an integral part of configuration, in addition to the standard printer command language (PCL). With standard ECP cabling, the product can use PJL to perform the following functions: ● Two-way communication with the host computer through a bidirectional parallel connection. The product can communicate information to the host (such as the control- panel status). ● Isolation of print environment settings from one print job to the next. For example, if a print job is sent to the product in landscape mode, the subsequent print jobs print in landscape only if they are formatted for landscape printing.

ENWW Formatter system 75 Scanner and ADF functions and operation

The following sections describe how the document scanner and the automatic document feeder (ADF) function.

Scanner functions The scanner uses a light source, a color-separation method, and a charge-coupled device array (CCD) to collect optical information about the document and transform that into an image file. The scanner consists of these elements: ● a lamp (cold-cathode fluorescent bulb) ● five mirrors and a lens ● a CCD

Scanner Glass

CCFL Lamp

600 ppi CCD

Lens

Figure 4-3. Optical diagram of scanner The scanner lamp illuminates a small strip of the document (called the raster line). The mirrors direct the light through the lens to the CCD. The CCD senses and records the light, creating an analog representation of the raster line. If the ADF is being used, the document then advances in the ADF to the next raster line. If the flatbed is being used, the scanner module advances to the next raster line. This advancing and collection process continues to the end of the sheet. The image data is collected in the motor controller board, where it is processed and sent to the formatter. The formatter then handles the image data, outputting it as a copy, sending it through the LIU as a fax, or directing it to the computer as scanner output. The image data collected for scans is 600 pixels per inch (ppi). The image data collected for copies is 300 ppi. Each pixel has 8 bits for each of the three colors (256 grayscale levels for each color) or a total of 24 bits per pixel (24-bit color).

76 Chapter 4 Operational overview ENWW Scanner operation At startup and periodically at other times, the scanner assembly moves systematically to locate its home position. It then calibrates to a white strip located under the glass at the right end of the scan tub. If the product detects a document in the ADF when a copy or scan is initiated (from the software or the control panel), the scan module moves to the left side of the scan tub and stops. The image is acquired as the paper is fed through the ADF past the scanner module. If no document is detected in the ADF, the scan module acquires the image from the flatbed glass while slowly moving within the scan tub.

ADF operation Standby (paper-loading) mode: In standby mode, the pickup roller is up and the stack-stop is down, preventing the user from inserting the original document too far. When a document is inserted correctly, the paper-present sensor detects its presence. The standard operation of the ADF consists of the pick, feed, and lift steps. Pick: When it receives a copy or scan command, the ADF motor engages the gear train to lower the pickup-roller assembly and raise the stack-stop. The first roller, called the pre-pick roller, moves the top few sheets forward into the ADF. The next roller is the pickup roller. This roller contacts the ADF separation pad, which separates multiple pages into single sheets. Feed: The single sheet continues through the path. Along the way, the form sensor, which is a set distance from the ADF glass, detects the sheet. This alerts the scanner to start when the page reaches the glass. The scanner acquires the image, one raster line at a time, until it detects the end of the page. The page is then ejected. The pick and feed steps are repeated as long as paper is detected in the ADF input tray. Lift: When no more paper is detected in the ADF input tray and the form sensor detects the trailing edge of the last page, the last sheet is ejected and the motor turns in a sequence that lifts the pick roller assembly to standby (paper-loading) mode again. The ADF will not function when the ADF lid is open. The paper path is incomplete if the ADF lid is lifted from the glass.

Figure 4-4. Document scanner path The paper-present sensor determines if paper is in the ADF. The form sensor detects the top and bottom edges of the document. One other sensor detects an open ADF door.

ADF jam detection The ADF has two sensors that detect paper. The paper-present sensor detects the presence of media in the ADF input tray. The form sensor detects media moving through the ADF. If a jam is detected, the ADF immediately stops the paper feeding and a jam message appears on the control-panel display. A jam can be detected under any of the following conditions: ● Document-feeder jam—When documents are detected in the ADF input tray, and a command to copy, scan or fax is received, the scan module travels to the left side of the scan assembly and stops beneath the ADF scanner glass. The ADF then attempts three times, or for about ten seconds, to advance the paper to the form sensor. If the paper does not advance, the scan module travels back to the home position on the right side of the scanner assembly. The message Document feeder mispick. Reload. appears on the control-panel display. ● Long-document jam—If the paper has advanced to trigger the form sensor, but the trailing edge is not detected within the time allowed for a 381-mm (15-inch) document (the maximum allowable page length for the ADF), the scanner returns to the home position at the right side of the scanner assembly. The message Doc feeder jam. Clear, Reload. appears on the control-panel display. ● Stall jam—When a page that is less than 381 mm (15 inches) long has advanced to the form sensor but has not left it within the expected time, the paper has probably stalled or jammed. The scanner returns to the home position at the right side of the scanner assembly. The message Doc feeder jam. Clear, Reload. appears on the control-panel display. ● Other—If the paper stops in the ADF and the scan module remains under the ADF scanner glass, an internal firmware error has probably occurred. This is usually remedied by cycling the power.

Engine control unit (power system) The engine control unit (ECU) coordinates all print engine activities, drives the laser, and coordinates print data from the formatter with the image-formation process. The ECU also includes the power supply and distribution circuitry.

Note In several other HP LaserJet products, the ECU is also known as the controller PCA or the dc controller PCA.

ENWW Printer functions and operation 79 The ECU controls the following systems and functions: ● Power system – ac power distribution – dc power distribution – high-voltage power distribution – low-voltage power distribution ● Paper motion and monitoring ● Motors – main motor (M1) – fan motor (FN1) ● Printer laser/scanner ● Image formation ● Fuser – temperature control – failure detection

80 Chapter 4 Operational overview ENWW Figure 4-6. ECU loads shows the various ECU loads.

Figure 4-6. ECU loads

Power system within the ECU The ac, dc, and high-voltage power supply circuits are all contained within the ECU. Ac power distribution The ac power circuitry supplies ac voltage whenever the power cord is connected to the ac power source. Ac voltage is distributed to the dc power supply circuitry and to the ac driver circuitry, which controls ac voltage to the fuser assembly heating element. Dc power distribution The dc power distribution circuitry, located on the ECU, distributes +3.3 Vdc, +5 Vdc, +24 Vdc, and +32 Vdc as follows:

ENWW Printer functions and operation 81 ● +3.3 Vdc: Formatter Laser/beam-detect circuitry ECU Photosensors LIU ADF sensors Control Panel

● +5 Vdc: Formatter ECU Laser/beam-detect circuitry LIU

● +24 Vdc: Printer paper-path motor Exhaust fan Laser/scanner motor Solenoid Formatter (routing only) High-voltage power supply Fuser safety circuit Scanner (CCD)

● +32 Vdc: ADF motor Scanner motor Formatter (routing only)

High-voltage power distribution The high-voltage power supply applies an overlap of dc and ac voltage to the primary-charging roller and the developing roller. This circuit also applies a positive or negative dc voltage to the transfer roller according to the instructions from the engine control unit.

82 Chapter 4 Operational overview ENWW This circuit also controls the image density by changing the primary ac voltage and the developing ac bias according to the print-density setting. Figure 4-7. High-voltage power supply circuit shows the high-voltage power supply circuit.

Figure 4-7. High-voltage power supply circuit Low-voltage power distribution The low-voltage power supply circuit converts ac power into +24 Vdc, +5 Vdc, and +3.3 Vdc as required by the printer. The +24 Vdc is divided into +24 V, which is supplied constantly from the low-voltage power supply circuit, and +24 U, which is supplied to the high-voltage power supply circuit and which acts as the door-open detection. When the top cover is open, the door-open switch (SW301) cuts the +24 U to the high-voltage power supply circuit. The circuit contains a fuse for overvoltage protection. FU101 breaks and cuts power if overcurrent flows through the power cord. FU102 (on 110-127 V models) breaks at a lower amperage, as required for lower-voltage units. In addition, the +24 Vdc and +3.3 Vdc power circuitry contains an overcurrent protection circuit that automatically shuts off dc voltage output to prevent power-supply failures if current flow is excessive or voltage generation is abnormal. The circuit automatically resets itself when the printer is turned off.

ENWW Printer functions and operation 83 Paper-motion monitoring and control The ECU controls paper motion in the printer by continuously monitoring the various paper sensors and coordinating the timing with the other print processes. For a detailed explanation of paper movement and the interaction of the photosensors and solenoid with the paper-motion process, see Printer paper-feed system.

Motors The ECU controls the motors. The main motor provides all of the paper movement in the printer. The fan motor rotates the fan to cool the printer.

Printer laser/scanner drive The laser/scanner system is controlled by the ECU, which sends laser control signals CNT0, CNT1, and CNT2, and by the formatter, which sends video signals /VDO1, VDO1, /VDO2, and VDO2.

Figure 4-8. Overview of laser/scanner operation

84 Chapter 4 Operational overview ENWW Image-formation system Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. Image formation consists of seven processes:

Figure 4-9. Image-formation block diagram

The seven image-formation processes 1. Conditioning stage (primary charging)—This process applies a uniform negative charge to the surface of the drum with the primary-charging roller, which is located in the print cartridge. The primary-charging roller is coated with conductive rubber. An ac bias is applied to the roller to erase any residual charges from any previous image. In addition, the primary charging roller applies a negative dc bias to create a uniform negative potential on the drum surface. The print density setting modifies the dc voltage. 2. Writing stage (scanning exposure)—During this process, a modulated laser diode projects the beam onto a rotating scanning mirror. As the mirror rotates, the beam reflects off the mirror, first through a set of focusing lenses, then off a mirror, and finally through a slot in the top of the print cartridge, and onto the photosensitive drum. The beam sweeps the drum from left to right, discharging the negative potential wherever the beam strikes the surface. This creates a latent electrostatic image, which later is developed into a visible image. Because the beam sweeps the entire length of the drum while the drum rotates, the entire surface area of the drum can be covered. At the end of each sweep, the beam strikes the beam-detect lens, generating the beam-detect signal (BD signal). The BD signal is sent to the ECU, where it is converted to an electrical signal that synchronizes the output of the next scan line of data. 3. Developing stage—During this process, the latent electrostatic image is present on the drum. The toner particles obtain a negative surface charge by rubbing against the developing cylinder, which is connected to a negative dc supply. The negatively charged toner is attracted to the discharged (exposed, grounded) areas of the drum, and it is repelled from the negatively charged (unexposed) areas. 4. Transfer stage—During this process, the toner image on the drum surface is transferred to the media. The transfer roller applies a positive charge to the back of the media, which attracts the negatively charged toner on the drum surface to the media. After separation, the drum is cleaned and conditioned for the next image. 5. Separation stage—During this process, the media separates from the drum. To stabilize the feed system and prevent toner dropouts on the printed image at low temperature and humidity, the static eliminator reduces the charge on the back of the media.

ENWW Printer functions and operation 85 6. Fusing stage—During this process, the heat and pressure fuse the toner into the media to produce a permanent image. The media passes between a heated fusing element and a soft pressure roller, which melt the toner and press it into the media. 7. Drum-cleaning stage—During this process, the cleaning blade is in contact with the surface of the drum at all times. As the drum rotates during printing, the cleaning blade wipes excess toner off the drum and stores it in the waste toner receptacle.

Print cartridge As the focal point of the image-formation system, the print cartridge contains toner and houses the cleaning, conditioning, and developing stages of the process. The print cartridge contains the photosensitive drum, primary charging roller, developing station, toner cavity, and cleaning station. By including these components (which wear, degrade, or are consumed) in the replaceable print cartridge, the need for many service calls is eliminated. The special photosensitive properties of the drum form an image on the drum surface and then transfer the image to media.

CAUTION The print cartridge does not include a light-blocking shutter. Do not expose the drum to light, which can permanently damage the drum. Protect the print cartridge whenever you remove it.

Printer paper-feed system The main input tray and the priority input tray merge into one main input area. Media placed in any of these areas activates the paper detection sensor (PS931), which informs the ECU that media is present. The following steps occur when the product receives a print job:

Step 1 The ECU activates the laser/scanner assembly and the motor. Paper motion begins when the ECU energizes the solenoid (SL1).

Step 2 The paper-pickup roller rotates once. The paper-lift plate pushes the media against the pickup roller.

Step 3 The pickup roller moves the top sheet and advances it to the feed assembly drive rollers. To ensure that only one sheet is fed, a main separation pad and two subpads hold the remainder of the stack in place.

Step 4 The feed-assembly drive rollers advance the media to the paper-top sensor (PS911). This sensor informs the ECU of the exact location of the leading edge of media, so that the image that is being written on the photosensitive drum can be precisely positioned on the page.

Step 5 The feed-assembly drive rollers then advance the media to the transfer area, where the toner image on the photosensitive drum is transferred to the media.

Step 6 After the image is transferred, the media enters the fuser assembly, where heat from the fuser and pressure from the pressure roller permanently bond the toner image to media. The paper-delivery sensor (PS921) determines that the media has successfully moved out of the fusing area.

Step 7 The fuser assembly exit rollers deliver media to either the paper output bin or the straight-through output path, according to the position of the straight-through output path door.

Figure 4-10. Printer paper path

Jam detection The paper-detection sensor (PS931) detects the presence of media in either the priority input tray or the main input tray. The paper-top sensor (PS911) and the paper-delivery sensor (PS921) detect media moving through the printer. If a jam is detected, the ECU immediately stops the printing process and a jam message appears on the control-panel display. A jam can be detected under any of the following conditions: ● Pickup delay jam—Media does not reach the paper-top sensor (PS911) after the pickup solenoid (SL1) has been turned on twice (the original pickup plus a retry) within 2 seconds. ● Pickup stationary jam—The paper-top sensor (PS911) does not detect the trailing edge of media within 1 second of detecting the leading edge. ● Delivery-delay jam—The paper-delivery sensor (PS921) does not detect the leading edge of media within 1.5 seconds after the paper-top sensor (PS911) detects the leading edge.

ENWW Printer functions and operation 87 ● Wrapping jam—The paper-delivery sensor (PS921) does not detect the trailing edge of the media within 0.1 second after the paper-top sensor (PS911) detects the leading edge and 1 second has passed since the paper-delivery sensor (PS921) detected the leading edge. ● Delivery-stationary jam—The paper-delivery sensor (PS921) does not detect the leading edge of media within 1.6 seconds after the paper-top sensor (PS911) detects the trailing edge. ● Residual paper jam—The paper-top sensor (PS911) or the paper-delivery sensor (PS921) detect media during the initial rotation period. ● Door open jam—The paper-top sensor (PS911) or the paper-delivery sensor (PS921) detect media while the print-cartridge door is open.

88 Chapter 4 Operational overview ENWW Fax functions and operation

The following sections describe the fax capabilities of the product.

PSTN operation The public switched telephone network (PSTN) operates by having a central office (CO) that generates a constant voltage on the TIP and RING wires (48 V, usually). A device goes on- hook by connecting impedance (such as 600 ohms for the U.S.) across TIP and RING, allowing a line current to flow. The CO can detect this current and can send impulses, such as dial tones. The product generates more signaling tones, such as dialing digits, to tell the CO how to connect the call. The product can also detect tones, such as a busy tone from the CO, that tell it how to behave. When the call is finally connected, the CO behaves as if it were a piece of wire connecting the sender and receiver. This is the period during which all of the fax signaling and data transfer occurs. When a call is completed, the circuit opens again and line current flow ceases, removing the CO connection from both the sender and the receiver. All of this is done with a two-wire arrangement. The two wires are called TIP and RING on all phone systems. On most phone systems, the wires appear on pins 3 and 4 of the RJ-11 modular jack (the one on the LIU). These two wires do not have to be polarized because all the equipment works with either TIP or RING on pin 3 and the other wire on pin 4. This means that cables of either polarity can interconnect and will still work. These are the basic functions of PSTN operation that are assumed in the design of the fax subsystem. The product generates and detects the signaling tones, currents, and data signals that are required to transmit and receive faxes on the PSTN.

The fax subsystem The formatter, LIU, firmware, and software all contribute to the fax functionality. The designs of the formatter and LIU, along with parameters in the firmware, determine the majority of the regulatory requirements for telephony on the product. The fax subsystem is designed to support V.34 fax transmission, lower speeds (such as V.17 fax), and older fax machines.

Formatter in the fax subsystem The formatter contains the modem chipset (DSP and CODEC) that controls the basic fax functions of tone generation and detection, along with channel control for the fax transmissions. The CODEC and its associated circuitry act to control transmit and receive gains, and to compensate for transmission signal coupling into the receive channel. The formatter also contains circuitry that adds termination impedance to help match the telephone network impedance.

LIU in the fax subsystem Two versions of LIU are used in the HP LaserJet 3380 all-in-one. One is used in the North American, South American, and Asian countries/regions. The other is used primarily in European countries/regions.

ENWW Fax functions and operation 89 The following are features that are different in the European version: ● a different voltage-protection device ● current limiting of the dc current ● filtering for the countries/regions that use billing or metering tones ● control of the impedance of the dc circuit through the SHUNT signal Because the TIP and RING are not polarized, all LIU circuitry that connects to TIP and RING is bidirectional. The LIU operates identically when TIP and RING are reversed.

Safety isolation The most important function of the LIU is the safety isolation between the high-voltage, transient-prone environment of the telephone network (telephone network voltage [TNV]) and the low-voltage analog and digital circuitry of the formatter (secondary extra-low voltage [SELV]). This safety isolation provides both customer safety and product reliability in the telecom environment. Any signals that cross the isolation barrier do so either optically or magnetically. The breakdown voltage rating of barrier-critical components is greater than 1.5 kV.

Safety-protection circuitry In addition to the safety barrier, the LIU protects against RING and over-current events. Telephone over-voltages can be either differential mode or common mode. The RING can be transient in nature (a lightning-induced surge or ESD) or continuous (a power line crossed with a phone line). The LIU protection circuitry provides margin against combinations of RING events. Common mode protection is provided by the selection of high-voltage-barrier critical components (transformer, relay, and optoisolators). The safety barrier of the LIU PCB traces and the clearance between the LIU and surrounding components also contribute to common mode protection. A voltage suppressor (a crowbar-type SIDACTOR) provides differential protection. This device becomes low impedance at approximately 300 V differential, and crowbars to a low voltage. A series thermal switch works in conjunction with the crowbar for continuous RING events, such as crossed power lines. When the differential RING is continuous, the resulting over-current causes the thermal switch to become high impedance, disconnecting RING from the network and protecting the crowbar from thermal overload. The thermal switch automatically resets to low impedance after the over-current condition is removed, reconnecting RING to the network.

Data path The magnetically coupled signals that cross the isolation barrier go either through a transformer or a relay. The TIP and RING signals use a transformer to cross the isolation barrier. TIP and RING are the two-wire paths for all signals from the telephone network. All signaling and data information comes across them, including fax tones and fax data. The telephone network uses dc current to determine the hook state of the telephone, so line current must be present during a call. On some line interfaces this current flows through the transformer, but on the LIU, a capacitor blocks the current from going into the transformer.

90 Chapter 4 Operational overview ENWW Blocking the current with a capacitor prevents the core of the transformer from being saturated by the high dc voltage, which can affect the ac signal quality. Rather than permitting the current to flow through the transformer, this LIU directs the current through another circuit called a gyrator or dc hold circuit. This creates the path for the central office-current flow when a call is in progress.

Hook state Another magnetically coupled signal is the control signal that disconnects the downstream telephone devices (such as a phone or answering machine). A control signal originating on the formatter can change the relay state, causing the auxiliary jack (downstream jack) to be disconnected from the circuit. The product takes control of calls that it recognizes as fax calls. If the product does not directly pick up the call, it monitors incoming calls for the fax tone or for the user to direct it to receive a fax. This idle mode is also called eavesdropping. This mode is active when the product is on- hook but current exists in the downstream phone line because another device is off-hook. During eavesdropping, the receive circuit is enabled but has a different gain from the current that is generated during normal fax transmissions. The product does not take control of the line unless it detects a fax tone or the operator tells it to connect manually. This feature allows the user to make voice calls from a phone that is connected to the product without being cut off if a fax is received.

Downstream current detection The aux phone detect signal is optically coupled. This signal tells the firmware that an active phone (or modem or answering machine) is connected to the auxiliary port of the product (the right side of the RJ-11 jack). A circuit that can detect current above a certain threshold generates the downstream-current- detection signal. The downstream current goes through a resistor, generating a voltage. If this voltage is above the threshold level, the signal changes state. The downstream-current-detection signal is coupled back to the formatter through an optoisolator and across the safety isolation barrier. The firmware uses this signal to ensure that the product does not go off-hook (and disconnect a downstream call) until it has been authorized to do so (by a manual fax start or detection of the appropriate tones).

Hook switch control Another optically coupled signal is the hook switch control. This signal from the formatter causes an optoisolator on the LIU to activate (making an open circuit into a short circuit). When shorted, the circuit is drawing dc current from the central office and is considered “on- hook.” When open, no dc current flows and the state is considered to be “off-hook.” For pulse dialing, the optoisolator is toggled on and off with a particular timing sequence to generate pulses that the central offices of the telephone company recognizes as dialing digits.

Ring detect Another optically coupled signal on the LIU is ring detect. Ring detect is a combination of voltage levels and cadence (time on and time off). Both must be present in order for the product to detect a valid ring. The LIU works with the firmware to determine if an incoming signal is an answerable ring. When circuits on the LIU detect a ring voltage above a certain threshold, a corresponding signal is passed to the formatter to indicate that the ring is above the threshold. The firmware then measures the amount of time that the signal is high and low, and qualifies the cadence to determine whether it is a valid ring.

ENWW Fax functions and operation 91 Line current control The dc current from the CO needs to have a path to flow from TIP to RING. Because the current does not flow in the transformer, a path through some transistors and diodes (the dc hold circuit) acts like a simulated inductor (thus replacing the function of the transformer). This dc hold circuit is the main component of the voltage-current characteristic between TIP and RING. Two other functions of this block of circuits are the current limit and the SHUNT for Europe. Current limit basically maintains a constant current from TIP to RING after the voltage reaches about 50 mA. Even if the voltage varies, the current will remain the same. The SHUNT function changes the impedance (the current-voltage characteristic) during certain special events, such as pulse dialing and when the devices goes on-hook. During such an event, the firmware tells the DSP on the formatter to activate SHUNT. A signal goes to the LIU through an optoisolator (optically coupled), which changes the state of some transistors so that the board has a linear current characteristic (normally, it is current- limited). Then more current can flow to the network, as required by these special events.

Billing (metering) tone filters Switzerland and Germany provide high-frequency ac signals on the phone line in order to bill customers. The LC (inductor, capacitor) notch filters are provided on the European LIUs to prevent these billing signals from adversely affecting the data path and the dc hold circuit. An additional filter in the cable (for certain countries/regions) can, in some cases, supplement these LC notch filters. Because these billings signals are not used in the U.S., these filters are not present on the U.S. LIU.

Fax page storage in flash memory Fax pages are the electronic images of the document page. They can be created in any of three ways: scanned to be sent to another fax machine, generated to be sent by the computer, or received from a fax machine to be printed. The product stores all fax pages in flash memory automatically. After these pages are written into flash memory they are stored until the pages are sent to another fax machine, printed on the product, transmitted to the computer, or erased by the user. These pages are stored in flash memory, which is the nonvolatile memory that can be repeatedly read from, written to, and erased. The product has 4 MB of flash memory, of which 3.4 MB is available for fax storage. The remaining 0.6 MB is used for the file system and reclamation. Adding RAM does not affect the fax page storage because the product does not use RAM for storing fax pages.

Stored fax pages The user can reprint stored fax pages in case of errors. Other fax devices store fax pages in either normal RAM or short-term RAM. Normal RAM immediately loses its data when power is lost, while short-term RAM loses its data about 60 minutes after a power failure. Flash memory maintains its data for years without any applied power.

Advantages of flash memory storage Fax pages stored in flash memory are persistent. They are not lost as a result of a power failure, no matter how long the power is off. Users can reprint faxes in case the print cartridge runs out of toner or the product experiences other errors while printing faxes.

92 Chapter 4 Operational overview ENWW The product also has scan-ahead functionality that makes use of flash memory. Scan-ahead automatically scans pages into flash memory before a fax job is sent. This allows the sender to pick up their original document immediately after it is scanned, eliminating the need to wait until the fax is transmission is complete. Because fax pages are stored in flash memory, not RAM, more RAM is available to handle larger and more complicated copy and print jobs.

Is Power-on successful? When the product is connected to a grounded power source, the words Hewlett Packard appear with moving cursors to indicate that the firmware code is loading, and the printer motor rotates for approximately 5 seconds. When the firmware is done loading (30 to 40 seconds after power-on), the message Scanner Bulb warming up appears on the control panel, and the scan head moves back and forth for 10 to 15 seconds. If you lift the lid, you will see that the scanner bulb is lit. Near the end of this time, the ADF motor turns on for about 2 seconds. Cause Solution

No power is available because of a failed power source, 1. Verify that the product is plugged in to a functional power cable, switch, or fuse. (No LEDs are lit and the display is source. blank.) 2. Verify that the power cable is functional and that the power switch is on. 3. Verify that FU101 (FU102 for 110-volt units) on the ECU is not open. 4.

ENWW Basic troubleshooting 165 Control-panel messages

The majority of the control-panel messages are intended to guide the user through normal operation. The control-panel messages indicate the status of the current operation, and include a page count on the second line of the display, if appropriate. When the product is receiving fax data, print data, or scanning commands, control-panel messages indicate this status. In addition, alert messages, warning messages, and critical error messages indicate situations that might require some action.

Note You must use the fax cord that came with the product in order to ensure that the product functions correctly.

Alert and warning messages Alert and warning messages appear temporarily and might require the user to acknowledge the message by pressing MENU/ENTER to resume or by pressing CANCEL to cancel the job. With certain warnings, the job might not complete or the print quality might be affected. If the alert or warning message is related to printing and the auto-continue feature is on, the product will attempt to resume the printing job after the warning has appeared for 10 seconds without acknowledgement.

Note Event-log codes are not listed here. For a list of event-log codes, see Event-log codes.

If the problem occurs when printing, see Solving print image-quality problems. If the problem occurs when copying or scanning, see Solving scanning (copying) image-quality problems. Also, see Solving print paper-feed problems and Jams occur in the automatic document feeder (ADF).

Checking the print cartridge Image-formation defects are frequently the result of problems in the print cartridge. If the source of the defect is not immediately evident, always replace the print cartridge before troubleshooting image defects. Use the following checklist to make sure that the print cartridge is still operable. □ Make sure that the print cartridge is seated properly. □ Check the print cartridge to see if it has been disassembled or refilled. □ Inspect the print cartridge to see if toner is leaking through worn seals. □ Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or scratched. Touching the drum contaminates the photosensitive surface and can cause spotting and image defects. □ Blurred areas on printed pages indicate that the photosensitive drum in the cartridge has been overexposed to light. Because overexposure to light causes permanent damage to the photosensitive drum, the cartridge should be replaced.

To redistribute the toner in the print cartridge Before installing a new print cartridge or when the toner begins to run low, redistribute the toner by rotating the cartridge back and forth five or six times.

Solving print image-quality problems Use the following tables to help solve problems with printed pages.

Note Some image-quality problems can be isolated by performing printer functional tests. See Functional checks. Image quality problems can also be caused by using cables that are not IEEE-1284 compliant.

ENWW Solving paper-feed problems 203 Solving problems with digital subscriber line (DSL) connections

A digital subscriber line (DSL) uses digital technology over standard copper phone wires. DSL services rely on an AM signal. The HP LaserJet 3380 all-in-one is a Group 3 fax device, which operates below the DSL capability and is not directly compatible with digital signals. However, if specified during the DSL line setup, the signal on a DSL line can be separated so that some of the bandwidth is used to transmit an analog signal (for voice and fax) while the remaining bandwidth is used to transmit digital data. Split the signal to use both the telephone or fax and the computer on the same line and at the same time.

Note Not all printers and faxes are compatible with DSL services. HP does not guarantee that the HP LaserJet all-in-one product will be compatible with all DSL service lines or providers.

The DSL modem requires a high-pass filter. Sometimes when DSL service is installed, the service provider supplies a splitter, which includes a low-pass filter, for the normal house phone wiring. If not, the user should contact the DSL provider, and request a filter or splitter to enable a fax modem to operate on the line.

Note HP recommends discussing DSL line setup options with the DSL service provider. Consult the DSL provider for technical installation requirements.

204 Chapter 6 Troubleshooting ENWW Connecting additional devices

Depending on how the phone lines are set up, additional devices can be connected to the phone line along with the HP LaserJet 3380 all-in-one. In general, no more than three devices should be connected to a single phone line. If too many devices are connected to a single phone line, one or more of the devices might not detect an incoming call. If this occurs, disconnect one or more of the devices.

Note This product cannot replace a computer modem. It cannot act as a modem for sending and receiving e-mail, for connecting to the Internet, or for communicating with other computers.

Dedicated fax line If the product is connected to a phone line that is used only for fax calls, the following devices can be connected: ● Caller ID box ● Modem—An internal or external computer modem can be connected to the fax line if the fax line is to be used for e-mail or access to the Internet. However, faxes might not be sent or received while the line is being used for these purposes. ● Extra phone—An extra phone line can be connected to the fax line if the fax is to be used for making outgoing calls. Do not connect an answering machine or computer voicemail system to the fax line. If the customer uses computer voicemail, connect the external or internal modem to the dedicated phone line. Then, use the dedicated voice line to connect to the Internet and receive voicemail.

Shared phone line If the product is connected to a phone line that is shared between fax calls and voice calls, or if the phone line has two phone numbers assigned and uses a ring-pattern service, the following devices can be connected: ● Caller ID box ● Modem—An internal or external computer modem can be connected to the fax line if the fax line is to be used for e-mail or access to the Internet. However, faxes might not be sent or received while the line is being used for these purposes. ● Phone—Connect a phone to the shared phone line to make or answer voice calls on the shared line. ● Answering machine or computer voicemail system—Connect these devices to the same phone jack that the product uses in order to make sure that the different devices do not interfere with one another.

Note It is possible to connect devices to another phone jack for the same phone line (for example, in another room). However, the devices might interfere with faxing and with each other.

To connect additional devices Connect additional devices in the order that is described in the following steps. The output port for each device is connected to the input port of the next device, which forms a "chain." Skip the steps for devices that the customer is not using, and continue to the next device.

ENWW Connecting additional devices 205 Note Do not connect more than three devices to the telephone line.

1. Unplug the power cords for all the devices that you want to connect. 2. Make sure that the product is connected to a telephone jack before continuing. 3. Open the print-cartridge door, and then open the left-side cover to reveal the fax ports.

4. Remove the plastic insert from the "telephone" port (the port that is marked with the telephone icon).

5. To connect an internal or external modem on a computer, plug one end of a telephone cord into the product “telephone” port. Plug the other end of the telephone cord into the modem “line” port.

Note Some modems have a second “line” port to connect to a dedicated voice line. If there are two “line” ports, see the modem documentation to verify which port is the correct “line” port.

Use the following procedures to help diagnose and solve problems that occur in the print engine.

Engine test The engine test is used to verify that the print engine is functioning correctly. The formatter is bypassed during an engine test, so the engine test is useful for isolating printer problems. The engine test prints horizontal lines down the entire printable area of a page and is also useful for checking and adjusting registration.

Printing an engine test The engine test switch is inside the left side door, below the formatter. To print an engine test, open the left side door and use a non-conductive probe to depress the engine test switch. A single test page will print.

CAUTION Use a non-conductive probe to depress the engine test switch. Inserting a conductive probe to depress the switch can damage the product.

Note The formatter must be connected to the ECU in order to perform an engine test. Otherwise, the printer does not print. You must override the print cartridge door interlock (SW 301). (See Paper-path check.)

After testing all of the control-panel buttons (or when there is no activity at the control panel for about 20 seconds), the product exits the test and continues the startup processes.

Half self-test functional check The purpose of the half self-test check is to determine which image-formation process is malfunctioning. The image-formation process can be subdivided into the following stages: ● conditioning stage (charges the drum) ● writing stage (writes a latent image to the drum with the laser) ● development stage (forms a toner image on the drum) ● transfer stage (transfers the image to paper) ● separation stage (separates the media from the drum) ● fusing stage (applies heat and pressure to make the image on paper permanent) ● cleaning stage (removes excess toner from the drum)

To perform a half self-test check 1. Print a self-test page. (See Troubleshooting tools.) 2. Open the print cartridge door after the paper advances halfway through the printer (about 5 seconds after the motor begins rotation). The leading edge of the paper should have advanced past the print cartridge. 3. Remove the print cartridge.

ENWW Functional checks 209 4. Open the print cartridge drum shield to view the drum surface. If a dark and distinct toner image is present on the drum surface, assume that the first three functions of the image- formation process are functioning (through the development stage). Troubleshoot the failure as a transfer or fusing problem.

To perform other checks If, during the half self-test check, no image is present on the photosensitive drum, perform these checks: 1. Make sure that you removed the entire length of the sealing tape from the print cartridge before you installed the cartridge. 2. Perform a drum-rotation functional check. (See Drum-rotation functional check .) 3. Perform a high-voltage power-supply check. (See High-voltage power-supply check.)

Drum-rotation functional check The photosensitive drum, which is located in the print cartridge, must rotate in order for the print process to work. The photosensitive drum receives its drive from the main drive assembly.

Note This test is especially important if refilled print cartridges have been used.

1. Open the print-cartridge door. 2. Remove the print cartridge. 3. Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the mark. 4. Install the print cartridge and close the print-cartridge door. The startup sequence should rotate the drum enough to move the mark. 5. Open the print-cartridge door and inspect the gear that was marked in step 3. Verify that the mark moved. If the mark did not move, inspect the main drive assembly to make sure that it is meshing with the print-cartridge gears. If the drive gears appear functional and the drum does not move, replace the print cartridge.

Heating-element check Paper passes between the heating element and a soft pressure roller to fuse toner to the paper. 1. Unplug the product for at least ten minutes. Remove the right cover (see Printer right-side cover) and back cover (see Back cover). 2. Verify that the thermistor connector is seated into both the product chassis and the ECU. 3. Unplug the fuser cable connector (callout 1) by pressing and releasing the tab on the back of the connector. To measure the continuity of the heating element, measure the resistance between the two pins at the end of the cable.

Note Normal resistance is 25 ohms +/- 10 ohms for the 110 V product and 80 ohms +/- 20 ohms for the 220 V product.

If no resistance is measured, replace the fuser.

210 Chapter 6 Troubleshooting ENWW 4. Remove the thermistor connector (callout 2), and measure the resistance between J206 pins one and two and between J206 pins three and four.

Note Normal resistance between both pairs of pins is 370 K ohms +/- 50 K ohms at 20° C (68° F).

If no resistance is measured, replace the fuser.

High-voltage power-supply check The high-voltage power-supply PCA provides the necessary voltages for the image-formation processes.

To check the print-cartridge connection points Turn the print cartridge over and visually inspect the three connection points on the ends of the print cartridge: one on the right side (callout 1), and two on the left side (callout 2). If they are dirty or corroded, clean the connection. If they are damaged, replace the print cartridge.

Note One of the connection points on the left side is underneath the print-cartridge shutter.

ENWW Functional checks 211 Note Use only isopropyl alcohol to clean the connections.

212 Chapter 6 Troubleshooting ENWW To check the high-voltage connector assembly The assembly uses three spring-loaded pins to contact the print cartridge: drum ground (callout 1), charging (callout 2), and developing roller (callout 3). Verify that the pins are not dirty or corroded and that the spring-loading action is functional. If the pins are dirty, clean them using isopropyl alcohol only. If they are damaged, replace the high-voltage connector assembly.

While SW301 and the laser/scanner interlock are engaged, perform an engine test or self-test to observe paper motion. See Engine test and Half self-test functional check.

214 Chapter 6 Troubleshooting ENWW Updating or recovering the firmware code

The product has a flash-memory-based formatter that enables the firmware code to be updated in the event that new firmware is released for the product. Using flash memory also provides a way to recover the firmware in the event of code corruption or failure.

Firmware update by using flash executable The configuration page lists the firmware version of the product. On flash-memory-based products, you can update the firmware code by downloading the latest flash executable for the product and running the program according to the readme instructions that come with it. Turn the printer off and then on before running the executable file. If the firmware becomes corrupted or fails (usually because of an interruption when attempting to update the firmware), the product no longer functions. In this case, a firmware-recovery DIMM is available from HP.

Firmware-recovery DIMM A firmware-recovery DIMM can be obtained from HP in the rare event that the firmware in flash memory becomes corrupted. When the DIMM is installed in the DIMM slot on the formatter and the product is turned on, the DIMM loads the latest firmware code into the product.

To use the firmware-recovery DIMM 1. Order a firmware-recovery DIMM (RDIMM) from HP. Retain the return mailer. 2. Turn off the product. 3. Open the left-side door, and install the firmware-recovery DIMM into the DIMM slot (callout 1).
